joint.

The object of my invention is to construct the universal joint in such manner that the bit-socket and crank can be set ata greater angle to each other than by the ordinary universal joint, and also to provide a detachable connection between the bit-stock and the crank,

so that thcangular socket can be removed and the brace be used as an ordinary brace by at taching a straight socket to the crank.

Theinvention consists of the improvements, which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of myii'nproved brace. Fig. 2is a front view thcreoi. Fig. 3 is a longitudinal sectional elevation of the lower portion of the brace on an enlarged scale. Fig. 4 is a fragmentary elevation showing an ordinary straight bit'sockct attached to the crank. Fig. 5 is an elevation of thelower end of the crank. Figs. 6, 7, and 8 are horizontal sections of the detachable connect-ion between the crank and bitsOcket, showing different positions of the parts.

Likelettors of rciercncercfer to like partsin the several figures.

A represents the bit-socket, which may be of any suit-able construction, and which is socured to the lower end of a vertical shank or spindle, a. The latter turns in a hearing, 1), formed at the lower end of an angular frame, (J, which supports the movable parts of the brace.

D is the crank, which is provided with a handle, cl, and at its outer end with a head, d, in the usual manner. The inner eudof the crank is dctachably secured to a sleeve, E, which turns in a bearing, 6, formed at the up per end of the angular supporting-frame G.

F represents the universal joint which consented in Fig. 3.

nccts the sleeve E with the shank not the bitsocket and whereby the rotary motion of the crank is imparted to the bit-socket. The crank D is provided at its inner end with a longitudinal slot or recess, g, which engages over a transverse pin or bar, 9, arranged in the bore of the sleeve E, near the upper end thereof.

represents transverse notches or recesses formed at the inner end of the slot 9, on opposite sides thereof and communicating therewith.

'Upon turning the lower end of the crank in one or the other direction the pin 9 engages in the transverse recesses g of the slot, as shown in Figs. 6 and 7. whereby the sleeve E is securely attached to the crank. Upon turning the crank so that the pin 9 clears the recesses g", as shown in Fig. 8, the sleeve with the frame 0 can be detached from the crank. The bit-socket A and its shank a are detachably connected in a similar manner, the bitsocket being provided nearits upper end with a pin, ii, and the shank with a longitudinal slot, it, having transverse recesses, as repre- By removing the frame 0 from the end of the crank and detaching the bit-socket from its shanlgthc bit-socket can be attached to the crank, as shown in Fig. 4, in which case the bitsocket stands in line with the crank and the brace operates as an ordinary straight brace. This construction forms a simple and inexpensive connection, which dispenses with the use of set-screws and other fastening devices and permits the parts to be easily and quickly interchanged to convert the brace from a corner brace to an ordinary brace, or vice versa. The universal joint F is composed of a ring or frame, c, which is pivoted between two jaws, '6, arranged at the upper end of the shank a, a ring or frame, j, which is pivoted between two similar jaws, j, arranged at the lower end of the sleeve E, and connecting-links 7.: k, pivoted at opposite ends to the rings i j. The jaws z" j are formed on collars i jflwhich are secured to the spindle a and sleeveE by pins or rivets f. The links k are connected between the rings by a crossbar, It, and their pivots are arranged at right angles to the pivots whereby the rings are at tached to the jaws i j.

L represents a handle secured to the supporting-frame O, and whereby the brace is steadied and guided when used as a corner brace. The handle L-is arranged out of line with or a short distance in rear of the bearing 1) of the bit-socket, as shown in Figs. 1 and 3, so that the hand of the operator will not come in contact with the wall or other object against which the bit-socket is placed.

By constructing the joint with the links 7a 7a the crank and bit-socket can be arranged at-a greater angle to each other than is possible when the rings are pivoted directly to each other, thereby removing the inner end of the crank 21 sufficient distance from the handle L to leave ample space between the handle and crank for the hand of the operator.

I claim as my invention- 1. The combination, with the bit-socket and a tubular supportingframe, 0, provided with a movable sleeve, E, having a'transverse pin or bar, of a crank provided at its end with a longitudinal slot engaging over said pin, and a transverse notch or recess communicating with said slot and in which said pin engages by turning the parts upon each other, substantially as set forth.

2. The combination, with the tubular bitsocket A, provided in its bore with a transverse pin, 71, of the crank D, provided in its end with a longitudinal slot, 9, having a trans verse recess, substantially as set forth.

3. The combination, with the supportingframe 0, of the bit-socket A and sleeve E, provided, respectively, with transverse pins h and g, the shank a and crank D, provided, respectively, with longitudinal slots h and having transverse recesses, and a universal joint connecting the sleeveE and shank a, substantially as set forth.

4.. The eomb'inatiomwith the bit-socket and its shank provided with jaws z", and the crank D, provided with a sleeve, E, havingjawsj, of the universal jointF,conneeting said sleeve and shank, and composed of a ring or frame, 2', pivoted to thejaws i, a ring orframe, j, pivoted to the jaws j,and connecting-links k, having their pivots arranged at right angles to the pivots of the rings, substantially as set forth.

5. The combination, with the bit-socket A, provided in its bore with a transverse pin, h, and the crank D, provided at its end with a longitudinal slot, g, of an angular detachable frame, 0, provided at one end with a movable sleeve, E, having a transverse pin, 9, adapted to engage with the slot 9 of the crank, and at its opposite end with a shank, a, havingalongitudinal slot, h, adapted to engage with the pin h of the bit-socket, auniversal joint, F, connecting theinner ends ofthe shank aand sleeve E, and a handle, L, secured to the frame 0, substantially as set forth.

6. The combination, with the bit-socket A and crank D, of the detachable angular frame 0, connecting the crank D and socket A, and provided with a handle, L, arranged in 'rear of the vertical plane of the socket A, substantially as set forth.

Witness my hand this 4th day of October, 1887.
